MFC r343348:
ocs_fc: Ensure that we zero-initialize memory before copying it out.

admbugs: 765

Issue:
Utility hangs when OCS_IOCTL_CMD_MGMT_GET_ALL called in parallel on port 0 and port 1.

Fix: Using static structure for results is corrupting the second ioctl request. Removed static for results structure.

Bring in the Broadcom/Emulex Fibre Channel driver, ocs_fc(4).

The ocs_fc(4) driver supports the following hardware:

Emulex 16/8G FC GEN 5 HBAS
LPe15004 FC Host Bus Adapters
LPe160XX FC Host Bus Adapters

Emulex 32/16G FC GEN 6 HBAS
LPe3100X FC Host Bus Adapters
LPe3200X FC Host Bus Adapters

The driver supports target and initiator mode, and also supports FC-Tape.

Note that the driver only currently works on little endian platforms. It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.

ocs_fc(4): Fix GCC build (-Wredundant-decls)

These objects are defined earlier in the same file; an extern declaration
after definition is redundant.

Broken in r331766 (introduction of ocs_fc(4)).
